«ANVIL is a free video annotation tool, developed by Michael Kipp. It offers multi-layered annotation based on a user-defined coding scheme. During coding the user can see color-coded elements on multiple tracks in time-alignment. Some special features are cross-level links, non-temporal objects, timepoint tracks, coding agreement analysis, 3D viewing of motion capture data and a project tool for managing whole corpora of annotation files. Originally developed for gesture research in 2000, ANVIL is now being used in many research areas including human-computer interaction, linguistics, ethology, anthropology, psychotherapy, embodied agents, computer animation and oceanography.

ANVIL can import data from phonetic tools like PRAAT which allow precise and comfortable speech transcription (see my video tutorial). Anvil can display waveform and pitch contour. Anvil's data files are XML-based. Exported tables can be used for analysis in statistical toolkits like SPSS or Statistica. The coming version will also be able to import ELAN files. ANVIL is written in Java and runs on Windows, Macintosh and Unix platforms.»

«A tool for building corpora of linked transcripts and digitised media.

Audiamus instantiates the links to digitised media. It requires no segmentation of the sound/video file. Currently there is no limit to the size of the media file or the number of transcripts. Each ’card’ of the current model represents a single transcript (typically a complete side of a cassette). Time-aligned transcripts, as produced for example by SoundIndex or Transcriber are the input for Audiamus.

The transcripts in Audiamus are plain text and can be edited, as can the timecodes. Thus the data in Audiamus is the master copy of the transcript that is improved incrementally with use. To avoid the problem of data being locked up in proprietary formats there is a mass export function that dumps all linked text and timecodes to plain text files, or to whatever format the user selects.»

«Prosogram is a tool for the analysis and transcription of pitch variations in speech. Its stylization simulates the auditory perception of pitch by the listener. A key element in tonal perception is the segmentation of speech into syllable-sized elements, resulting from changes in the spectrum (sound timbre) and intensity. The tool also provides measurements of prosodic features for individual syllables (such as duration, pitch, pitch movement direction and size), as well as prosodic properties of longer stretches of speech (such as speech rate, proportion of silent pauses, pitch range, and pitch trajectory). The tool can easily interact with other software tools. It is used as the first step in automatic phonological transcription of intonation, the detection of sentence stress and intonation boundaries.

Processing steps:

  • Calculate acoustic parameters: F0, intensity, voicing (V/UV).
  • Obtain a segmentation into units of the types indicated above. Select the relevant units (e.g. vowels, syllables). Select the voiced portion of these units, that has sufficient intensity/loudness (using difference thresholds relative to the local peak).
  • Stylize the F0 of the selected time intervals.
  • Determine pitch range used in speech fragment. Plot stylized pitch and some annotation tiers (text, phonetic transcription). Use a musical (semitone) scale and add calibration lines at every 2 ST for easy interpretation of pitch intervals.

The system is implemented as a Praat script.»

«SegProso is a Praat-based tool for the automatic segmentation of speech corpora into prosodic units:

«The program SONA is a versatile experimental tool for finding and visualizing relevant information in both the time and the frequency domain of a speech signal.

In the time domain, the program allows:

  • digital recording of speech of nearly unlimited length with16 bit quantization
  • oscillographic representation with freely scaleable time and amplitude resolution
  • all kinds of signal manipulation (waveform editing)
  • reproduction of single or concatenated speech segments
  • measurement of their duration and intensity

Furthermore, the segments can be marked and transcribed phonetically (Labeling).

In the frequency domain (lower half of the screen), the program generates a digital spectral analysis of the speech signal in 2D or 3D. The 3D representation of the time dependent power spectrum is known as Visible Speech or sonagram and is one of the most important practical tools of linguistics and phonetics. Sonagrams are represented in gray scale or colour coding in one of five frequency sections (0.5 to 8 KHz) with variable breadth. One mouse click enables the user to listen to a selected segment or measure frequency and intensity of its spectrum.»

It can be used as a stand-alone tool for a wide range of tasks in speech research and education. Typical applications are speech/sound analysis and sound annotation/transcription. WaveSurfer can also serve as a platform for more advanced/specialized applications. This is accomplished either through extending the WaveSurfer application with new custom plug-ins or by embedding WaveSurfer visualization components in other applications.

«Windows EDW (WEDW) is a fundamentally new program which attempts to provide similar functionality to the Unix/DOS version (EDW), but with a very different user interface.

WEDW retains some of the appearance of EDW in that a waveform display region is always present while spectrogram and pitch marking windows can be toggled on and off as desired. Both EDW and WEDW read and write waveforms in an extended RIFF (Microsoft .WAV) format that includes waveform segment definitions and both are also able to read an older .WAV format that was the original format used by EDW.

  • Waveform
  • Labels
  • Spectrogram
  • Pitch Tracking

WEDW provides a way to display special symbols such as IPA phonetic symbols when a font for the symbols is available.

Prosodic features of duration, F0, and amplitude can be changed.»

«WinCECIL is a speech analysis tool based on the DOS CECIL version 2.1 program. WinCECIL provides support for recording, analyzing, and saving of 3 second sections of speech. WinCECIL requires a 20MHz 80386 computer or better running Microsoft Windows 3.1 or higher. It also requires a Windows Multimedia-compatible sound card.

Use this program to view speech recordings, automatic pitch contours, and spectrograms. Recording limit is 3 seconds.

Most of the functions of the WinCECIL program has been superseded by the Speech Analyzer program. This product has been discontinued and is no longer supported.»

  • «WinPitchW10 for prosodic research, with on the fly aligner, real-time spectrograph, multi-tracking F0 analysis, video and audio analysis, and much more.
  • WinPitch LTL W8 for language teaching, with all the features of WinPitch Pro plus authoring functions to produce and test pronunciation lessons for learners.
  • WinPitch LTL Only a dedicated version for language learners, using pronunciation exercises prepared with WinPitch LTL. Includes an automatic aligner for error detection and prosodic morphing functions.

All these versions run under Windows® XP, Vista, Windows 7 and Windows 8. They also run on a Mac computer with an appropriate Windows emulator installed (such as BootCamp)»

«For several years we have undertaken the development of the software WinSnoori which is for both speech scientists as a research tool and teachers in phonetics as an illustration tool. It consists of five types of tools:

  • to edit speech signals
  • to annotate phonetically or orthographically speech signals. WinSnorri offers tools to explore annotated corpora automatically
  • to analyse speech with several spectral analyses and monitor spectral peaks along time
  • to study prosody. Besides pitch calculation it is possible to synthesise new signals by modifying the F0 curve and/or the speech rate
  • to generate parameters for the Klatt synthesiser (in the Motif version). A user friendly graphic interface and copy synthesis tools allows the user to generate files for the Klatt synthesiser easily.»

«xassp is an application for displaying, analysing and processing speech signals. It is intended for segmental and prosodic labelling, but can be used for different purposes, because of its numerous configuration possibilities.

User-definable configurations allow to open several associated files together and to automatically perform certain analyses of the speech signal. The configuration Segmental, e.g. is intended for segmental labelling. The windows that are opened when choosing this configuration are:

  • a speech signal that can be selected in the main dialog
  • a sonagram that is computed by means of spectral analysis of the speech signal
  • the labels that are associated with the speech signal

The configuration Prosodic is used for prosodic labelling. When choosing this configuration the following windows are opened:

  • the selected speech signal
  • the fundamental frequency computed from the speech signal
  • the labels that are associated with the speech signal

Although xassp is mainly intended for segmental and prosodic labelling, it provides several additional possibilities for analysing speech signals:

  • Fundamental frequency (F0): The fundamental frequency can be displayed in different ways (range, linear or logarithmic scale)
  • Energy
  • Sonagram (FFT and LPC)
  • Section (FFT and LPC)»

Darrera actualització:

When we speak, we subconsciously listen to vowel and consonant sounds to ensure we're producing them correctly. If our speech is slightly different from what we intended, we adjust the way we speak to correct for these slight errors.

For some of us, detecting these errors or making the necessary adjustments can be a challenge. That's why we developed the icSpeech Analyzer.

How does the speech analyzer work?

icSpeech Analyzer uses the clinically proven technique of biofeedback to help improve your speech. Biofeedback lets you see your speech on a computer screen in real-time. At first, you learn to control your speech while looking at the display and comparing your speech to an example. Then, with practise, you learn to control your speech without looking at the display.

icSpeech Analyzer supports the following biofeedback displays:

You can also record your speech, create target displays, and perform measurements on a range of speech parameters.

Waveform displays

Waveform displays are useful for controlling speech rate, loudness and pitch. They also show the difference between voiced consonants, voiceless consonants and vowel sounds.

Waveforms scan across the display from right to left, with intensity or frequency plotted vertically and time horizontally. The time taken to scan the entire display can be adjusted to suit your needs.

The above example shows a speech waveform (top) and a voice intensity waveform (bottom). This example clearly illustrates the difference between the voiced sound /b/ and the unvoiced sound /p/.

You can also save the waveform display and perform precise measurements on a range of speech parameters, including:

  • Speech rate (independent of pauses or dysfluencies).
  • Speech intensity (loudness).
  • Voice pitch.
  • Voice intensity.
  • Voice onset time.
  • Sentence, word, syllable and phoneme duration.

Speech Analysis Format

Bar displays

The real-time bar is a useful biofeedback tool that shows a simple bar, which moves upwards with increased pitch, loudness or voice intensity. This allows you to monitor your speech, make corrections, and instantly see the result. Bar charts are particularly useful when working with sustained sounds.

The above example shows pitch (yellow bar) and a target (blue bar). Targets are adjustable bars that appear next to the active bar. Depending on the task, you can try to keep below, reach or exceed the target.

Video displays

Mirrors are often used in speech therapy as they allow you to view lips, teeth, jaw, tongue and facial muscles during speech.

Visual feedback, using the built-in webcam feature, takes this a step further. With a webcam you can:

  • Pause your image for closer inspection.
  • Record your video and audio.
  • Practise your speech whilst watching example recordings.

Spectrogram displays

A spectrogram is a visual representation of sound. It scans across the display from right to left, with frequency plotted vertically and time horizontally. The intensity of sound, or loudness, is indicated by grey scale or color intensity. The spectrogram below clearly shows the difference between the /r/ sound and the /w/ sound.

Studies have shown that some people, especially children, have difficulty detecting when they misproduce certain sounds. Spectrograms provide additional feedback, helping you to match your speech to a visual target. At first, you rely on visual feedback and learn to ignore your auditory feedback (people often say their correct speech production sounds wrong). Once you've mastered the correct speech production, you can start to rely more on your auditory feedback and less on the visual feedback.

Spectrograms can be particularly useful for people that substitute the following sounds:

  • /w/ for /r/
  • /w/ for /l/
  • /m/ for /b/
  • /p/ for /b/
  • /s/ for “sh” or vice versa

Spectrum displays

The spectrum display provides an alternative method of visually representing the acoustic signal. The display is ideal for viewing fundamental frequency (pitch), harmonic frequencies, and formant frequencies (vocal tract resonances). Speech intensity, or loudness, is plotted vertically and frequency horizontally.

The above displays illustrate the frequency spectrum for the vowel sound /i/. The top display (FFT) shows the fine spectral detail associated with the fundamental frequency and its harmonics. The bottom display (LPC), highlights the formant frequencies by removing the fundamental and harmonic frequencies.
